We are not even halfway through 2015, and police have shot and killed nearly 400 people, reports The Washington Post.

In an independent analysis of police killings in the United States this year, the Washington Post estimated that approximately 385 people have been shot and killed by police officers.

That estimate is nearly double what the federal government has reported for the time between January 1 and May 31 of every year in the last decade. Many experts and officials believe that law enforcement agencies underreport cases of officers using deadly force.

This analysis is the Washington Post’s attempt to produce a more accurate estimate of annual police killings.

“These shootings are grossly underreported,” said former police chief Jim Bueermann. “We are never going to reduce the number of police shootings if we don’t begin to accurately track this information.”
